Description

A crucible storage and retrieval device and a total moisture testing system Technical Field

[0001] This utility model relates to the field of sample total moisture determination technology, and in particular to a crucible storage and retrieval device and a total moisture testing system. Background Technology

[0002] During the coal mining and processing, changes in the moisture content of coal can lead to variations in the content of other components and calorific value, thus affecting coal quality inspection, measurement, acceptance, and management. Therefore, it is necessary to analyze the moisture content of coal samples.

[0003] A moisture analyzer is a specialized instrument used to measure the moisture content of a substance. Therefore, in current technology, moisture analyzers are commonly used to test the moisture content of coal samples. Moisture analyzers use crucibles to load samples for relevant chemical analysis. Crucible storage cabinets are used to store unused or used crucibles. However, crucible storage and retrieval operations are frequent, and the used crucibles are still hot, posing a risk of burns to workers. If the crucibles are not cooled before the next test, the accuracy of the test results will be affected.

[0004] In existing technologies, robotic arms are typically used to pick up crucibles and place them in designated locations to avoid scalding workers. However, the robotic arms need to be precisely positioned to the exact location of each crucible, placing high demands on their travel and control. This results in difficulties in crucible positioning and slow retrieval speeds, leading to low measurement efficiency. Furthermore, if crucibles are not retrieved in the correct order, it can easily cause confusion in their usage sequence, resulting in the use of uncooled crucibles for testing. Summary of the Invention

[0005] The purpose of this invention is to provide a crucible storage and retrieval device and a full moisture testing system. The crucible storage and retrieval device can hold a large number of crucibles and can remove the crucibles in sequence, so that each crucible has a longer cooling time, while facilitating the handling of crucibles by a robotic arm.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On the one hand, a crucible storage and retrieval device is provided, comprising:

[0008] The cabinet has a storage entrance and a retrieval exit.

[0009] At least two placement trays are provided inside the cabinet. All the placement trays are arranged at intervals along the vertical direction. Each placement tray has multiple placement positions for placing crucibles arranged at intervals along the circumference of the placement tray.

[0010] At least two drive mechanisms are provided, each corresponding to and connected to the placement disk, and the drive mechanisms are capable of driving the placement disk to rotate around the central axis.

[0011] Optionally, the driving mechanism includes a motor and a rotating shaft. The motor is positioned above the corresponding placement tray and is fixed relative to the cabinet. The motor is driven and connected to the rotating shaft, and the placement tray is fixedly connected to the rotating shaft.

[0012] Optionally, the motor drive is connected to the first end of the rotating shaft, the second end of the rotating shaft extends downward and is rotatably connected to another motor adjacent to the rotating shaft, the uppermost motor is fixedly connected to the inner wall of the cabinet, the lowermost rotating shaft is rotatably connected to the inner wall of the cabinet, the placement tray is provided with mounting holes, and the placement tray is sleeved on the rotating shaft through the mounting holes.

[0013] Optionally, the crucible storage and retrieval device further includes at least two fixing members, each corresponding to a motor. The motor is fixedly connected to the fixing member, and the rotating shaft is rotatably connected to another fixing member corresponding to the motor adjacent to the rotating shaft.

[0014] Optionally, the crucible storage and retrieval device further includes a support member, which includes a fixing ring and a support rod. The fixing ring is interference-fitted onto the rotating shaft, and one end of the support rod is connected to the fixing ring, while the other end is connected to the side wall of the mounting hole.

[0015] Optionally, the crucible storage and retrieval device further includes a plurality of temperature detection elements, each corresponding to a placement position and placed within the placement position, the temperature detection elements being used to detect the temperature of the crucible.

[0016] Optionally, the crucible storage and retrieval device further includes a control component electrically connected to the temperature detection element and the drive mechanism.

[0017] Optionally, the crucible storage and retrieval device further includes multiple photoelectric detection elements, which are disposed on the placement tray and correspond one-to-one with the placement positions. The photoelectric detection elements are electrically connected to the control component and are used to detect whether the crucible is placed in the placement position.

[0018] Optionally, the cabinet is provided with heat dissipation holes at both ends of the vertical direction.

[0019] On the other hand, a full moisture testing system is provided, including a crucible, a robotic arm, and the crucible storage and retrieval device described above. The crucible is placed in the placement position, and the robotic arm is disposed outside the cabinet. The robotic arm is capable of grabbing the crucible through the storage inlet or the retrieval outlet.

[0020] The beneficial effects of this utility model are:

[0021] This invention provides a crucible storage and retrieval device and a total moisture testing system. The crucible storage and retrieval device includes a cabinet, at least two placement trays, and at least two drive mechanisms. The placement trays are housed within the cabinet, and all trays are arranged vertically at intervals. Each tray has multiple placement positions for crucibles spaced out circumferentially. This arrangement increases the number of placement positions 21 while reducing the area occupied by the crucible storage and retrieval device, saving space. The cabinet has a storage inlet and an outlet. The storage inlet is used to place crucibles into the placement positions, and the outlet is used to remove crucibles from the placement positions. Each drive mechanism corresponds to and is driven by one of the placement trays, and the drive mechanism can drive the placement tray to rotate around a central axis. When storing crucibles, they are placed from the storage inlet to their corresponding positions. A drive mechanism rotates the placement tray, aligning the storage inlet with different placement positions sequentially, thus placing the crucibles in each position. When retrieving crucibles, the same drive mechanism rotates the placement tray, aligning the placement positions with the retrieval outlets sequentially, allowing the crucibles to be retrieved in sequence. Crucibles placed in their initial positions will rotate to the retrieval outlet first, ensuring sequential placement and retrieval. This allows each crucible sufficient cooling time, preventing overheating during retrieval. Furthermore, each placement tray has its own drive mechanism, enabling independent rotation without interference between trays. This makes crucible retrieval more flexible, reduces retrieval time, and improves efficiency. Additionally, the robotic arm only needs to move to the storage inlet or retrieval outlet, eliminating the need to pinpoint the exact location of each crucible, facilitating control and further enhancing retrieval efficiency.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] As shown in Figures 1-4, this embodiment provides a crucible storage and retrieval device, including a cabinet 1, at least two placement trays 2, and at least two drive mechanisms 3. The placement trays 2 are disposed within the cabinet 1, and all placement trays 2 are arranged sequentially at intervals along a vertical direction. Each placement tray 2 has multiple placement positions 21 for placing crucibles 100 spaced out in a circumferential ring. This arrangement increases the number of placement positions 21 and reduces the area occupied by the crucible storage and retrieval device, saving space. The cabinet 1 is provided with a storage inlet 11 and a retrieval outlet 12. The storage inlet 11 is used to place crucibles 100 into the placement positions 21, and the retrieval outlet 12 is used to remove crucibles 100 from the placement positions 21. The drive mechanisms 3 correspond one-to-one with the placement trays 2 and are driven and connected to the placement trays 2. The drive mechanisms 3 can drive the placement trays 2 to rotate around a central axis.

[0040] When storing crucible 100, it is placed from the storage inlet 11 into its corresponding placement position 21. The drive mechanism 3 drives the placement tray 2 to rotate, so that the storage inlet 11 sequentially aligns with different placement positions 21, thus placing the crucible 100 sequentially into the placement positions 21. When removing crucible 100, the drive mechanism 3 drives the placement tray 2 to rotate, so that the placement positions 21 sequentially align with the removal outlet 12, thus removing the crucible 100 sequentially. The crucible 100 placed in the placement position 21 first will rotate to the removal outlet 12 first, thus achieving sequential placement and removal of crucible 100. This allows each crucible 100 sufficient cooling time, preventing the removed crucible 100 from overheating. Furthermore, each placement tray 2 corresponds to a drive mechanism 3, allowing each placement tray 2 to rotate independently without interfering with each other. This makes the removal of crucible 100 more flexible, reduces removal time, and improves removal efficiency. In addition, the robotic arm only needs to move to the storage inlet 11 or the retrieval outlet 12, without needing to be positioned at the specific location of each crucible 100, which facilitates the control of the robotic arm and further improves the retrieval efficiency.

[0041] Specifically, the cabinet 1 has a cylindrical structure. Storage inlet 11 and retrieval outlet 12 are correspondingly located on the side walls of the cabinet 1. Both storage inlet 11 and retrieval outlet 12 are elongated and extend vertically, corresponding vertically to each placement tray 2, so that the crucible 100 on each placement tray 2 can be placed in through the storage inlet 11 or retrieved through the retrieval outlet 12. The width of the storage inlet 11 and retrieval outlet 12 matches the size of the placement position 21, so that the storage inlet 11 and retrieval outlet 12 correspond horizontally to one placement position 21. The placement tray 2 has a ring-shaped structure. Five placement trays 2 are provided, arranged vertically at intervals. The spacing between two adjacent placement trays 2 is set according to specific circumstances to ensure that the robotic arm can place or retrieve the crucible 100, and the interval arrangement also improves the heat dissipation rate of the crucible 100, reducing the cooling time. In other embodiments, the number of placement trays 2 can be two, three, four, six, or more. The placement position 21 is a groove formed on the placement tray 2. The horizontal cross-section of the placement position 21 is circular, and the sidewalls of the placement position 21 gradually slope outward from bottom to top. When the crucible 100 is placed on the placement position 21, the outer wall of the crucible 100 abuts against the sidewall of the placement position 21 to prevent the crucible 100 from moving when the placement tray 2 rotates. The number of placement positions 21 is set according to specific circumstances, and this embodiment does not limit this. The drive mechanism 3 is provided with five positions.

[0042] Optionally, the drive mechanism 3 includes a motor 31 and a rotating shaft 32. The motor 31 is positioned above the corresponding placement tray 2 and is fixed relative to the cabinet 1. The motor 31 is driven and connected to the rotating shaft 32. The placement tray 2 is fixedly connected to the rotating shaft 32. The motor 31 drives the rotating shaft 32 to rotate, thereby causing the placement tray 2 to rotate.

[0043] Furthermore, motor 31 is driven and connected to the first end of rotating shaft 32. The second end of rotating shaft 32 extends downward and is rotatably connected to another motor 31 adjacent to rotating shaft 32. The uppermost motor 31 is fixedly connected to the inner wall of cabinet 1, and the lowermost rotating shaft 32 is rotatably connected to the inner wall of cabinet 1, facilitating the fixation of motor 31. The placement tray 2 is provided with mounting holes 22, through which the placement tray 2 is fitted onto rotating shaft 32, allowing the placement tray 2 to rotate around rotating shaft 32. This configuration is simple in structure, easy to install, and saves installation space.

[0044] Specifically, the axes of the five rotating shafts 32 are located on the same straight line, so that the axes of the placement positions 21 on different placement trays 2 are also located on the same straight line, which facilitates the robotic arm to remove the crucible 100 from the placement position 21. In other embodiments, five mounting brackets can also be arranged vertically at intervals on the inner wall of the cabinet 1, and the motor 31 can be mounted on the mounting brackets to fix the motor 31.

[0045] Optionally, the crucible storage and retrieval device also includes at least two fixing parts 4, each corresponding to a motor 31. The motor 31 is fixedly connected to the fixing part 4, and the rotating shaft 32 is rotatably connected to the fixing part 4 corresponding to another motor 31 adjacent to the rotating shaft 32. By setting the fixing parts 4, it is convenient to connect the motor 31 and the rotating shaft 32, thereby improving the fixing strength and stability of the motor 31.

[0046] Specifically, the fixing member 4 is a plate-shaped structure. Five fixing members 4 are provided. The fixing members 4 are fixed to the upward-facing side of the motor 31 by welding or screw connection. The crucible storage and retrieval device also includes bearings, five of which correspond one-to-one with the rotating shaft 32 and are installed at the second end of the rotating shaft 32. The second end of the rotating shaft 32 is rotatably connected to the fixing member 4 via the bearings. The second end of the lowest rotating shaft 32 is rotatably connected to the bottom wall of the cabinet 1 via a bearing.

[0047] Optionally, the crucible storage and retrieval device further includes a support member 5, which includes a fixing ring 51 and a support rod 52. The fixing ring 51 is interference-fitted onto the rotating shaft 32, and one end of the support rod 52 is connected to the fixing ring 51, while the other end is connected to the side wall of the mounting hole 22. By providing the support rod 52, it is convenient to fix the placement plate 2 to the rotating shaft 32.

[0048] Specifically, four support rods 52 are provided, and the four support rods 52 are arranged circumferentially around the fixing ring 51. The support rods 52 can be fixed to the fixing ring 51 and the placement plate 2 by means of welding, snap-fit, or threaded connection, etc., and this embodiment does not limit this.

[0049] Optionally, the crucible storage and retrieval device also includes multiple temperature detection elements 6, which correspond one-to-one with the placement positions 21 and are placed in the placement positions 21. The temperature detection elements 6 are used to detect the temperature of the crucible 100 to ensure that the crucible 100 that has been cooled is taken out, and to avoid accidentally taking out the crucible 100 with a higher temperature.

[0050] Specifically, the temperature detection element 6 is a temperature sensor. The temperature detection element 6 is installed at the bottom of the tank in the placement position 21. When the crucible 100 is placed on the placement position 21, the bottom of the crucible 100 is above the temperature detection element 6, so that the temperature of the crucible 100 can be detected by the temperature detection element 6.

[0051] Optionally, the crucible storage and retrieval device further includes a control component, which is electrically connected to the temperature detection element 6 and the drive mechanism 3. The temperature detection element 6 transmits the detected temperature signal to the control component, which then controls the drive mechanism 3 to rotate the placement position 21 of the crucible 100 (which has a lower temperature) to the retrieval outlet 12 to remove the crucible 100. Specifically, the control component is a mature technology in the relevant field, and will not be described in detail here.

[0052] Optionally, the crucible storage and retrieval device further includes multiple photoelectric detection elements. These elements are disposed on the placement tray 2 and correspond one-to-one with the placement positions 21. The photoelectric detection elements are electrically connected to the control component. They are used to detect whether a crucible 100 is placed in the placement position 21. The detected signal is transmitted to the control component, which then controls the drive mechanism 3 to rotate the placement position 21 (where no crucible 100 is placed) to the storage inlet 11, thus placing the crucible 100 in the placement position 21. In this embodiment, the photoelectric detection element is a photoelectric sensor.

[0053] Optionally, as shown in Figures 1 and 5, heat dissipation holes 13 are provided at both ends of the cabinet 1 along the vertical direction. The heat dissipation holes 13 at both ends form air convection, which accelerates the cooling rate of the crucible 100 and reduces the cooling time of the crucible 100. Furthermore, efficient heat dissipation of the crucible 100 can be achieved without the need for a separate cooling device. Specifically, a plurality of heat dissipation holes 13 are provided, and the plurality of heat dissipation holes 13 are evenly distributed at the middle positions of the top and bottom of the cabinet 1.

[0054] As shown in Figures 1-5, this embodiment also provides a total moisture testing system, including a crucible 100, a robotic arm, and the aforementioned crucible storage and retrieval device. The crucible 100 is placed in the placement position 21, and the robotic arm is located outside the cabinet 1. The robotic arm can grasp the crucible 100 through the storage inlet 11 or the retrieval outlet 12. When storing the crucible 100, the control component controls the drive mechanism 3 to rotate the placement position 21 (where no crucible 100 is placed) to the storage inlet 11. The robotic arm extends into the cabinet 1 through the storage inlet 11 and places the crucible 100 in the placement position 21. When retrieving the crucible 100, the control component controls the drive mechanism 3 to rotate the placement position 21 (where the crucible 100 has a lower temperature) to the retrieval outlet 12. The robotic arm extends into the cabinet 1 through the retrieval outlet 12 and retrieves the crucible 100, thus improving the efficiency of crucible storage and retrieval.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
